I was thinking of various scenarios but that ending just blew it out of the water. When she left the hospital after Zoe told her she had the hard evidence, I had expected her to drive straight to the Rehab clinic. In fact I thought just before Grace walked out that that was the Rehab place. Then I figured after the accident scene that she would drive to the Rehab clinic. When she did not zip the suitcase shut I new something was up. The pills flying around seemed to be a ode the opening credits with pills everywhere. Its hard to believe she could go into Diversion now with the cops catching all the pills in the car. I suppose they could do like Shameless and send her to Jail for a while but at this point its seems that there is no way her license is not revoked. Perhaps the next season is all in prison and nobody but she comes back!
